How To Read This Page
CenoteTracker is built with the help of many open-source software projects. We are grateful to their maintainers and contributors. This page summarizes the most significant components and their licenses; it is not exhaustive.
This page covers only the components that we distribute as part of the mobile application — that is, the code that runs on your device. Server-side software that we operate as a service is not redistributed and is not listed here.
For a current machine-generated list of every dependency, please email [email protected].
